Objectives: Adolescent idiopathic scoliosis (AIS) is a complex three-dimensional spinal deformity associated with low bone mass. Our previous clinical trial demonstrated the anabolic bone effect of vibration treatment (VT) at the femoral neck in AIS subjects. The therapeutic effect was more pronounced in those with optimal serum 25(OH) Vit-D level (>40 nmol/l). To investigate possible factor interaction between Vit-D and VT on their anabolic bone effects, this in-vitro...

Tumour necrosis factor receptor-associated factor 6 (TRAF6) plays a key role in osteoclastogenesis through the regulation of RANK/CD40 TRAF6-mediated signaling. Mice deficient in TRAF6 exhibit high bone mass and were protected against inflammation-induced bone loss. Here we describe the effects of a small-molecule 6877002 that has been shown to prevent the binding of TRAF6 to its domain on RANK/CD40 receptor on osteoclast formation in vitro and in vivo and on...

Introduction: Osteoporosis is the musculoskeletal disease, the most common complication of liver osteodystrophy. Combined with vitamin D deficiency, they expose the patient to increased risk of fracture, increased morbidity and impaired quality of life.The objective of the study is to evaluate the vitamin D status and the prevalence of densitometric osteoporosis in 100 patients followed for chronic liver diseases.Materials and meth...

Objectives: Nutritional Rickets (NR) is the commonest cause of rickets worldwide. Although the prevalence of rickets has been widely reported to be increasing, the actual national incidence of NR in the United Kingdom (UK) is unknown.Methods: Retrospective data were collected monthly between March 2015 and March 2017 from 3500 consultant paediatricians using British Paediatric Surveillance Unit (BPSU) reporting methodology. Clinicians completed an online...

Objective: We investigated the effect of creatine administered in the diet for 10 weeks on bone turnover and bone quality in male Wistar rats.Methods: Rats were divided (after approval of Ethical committee 9814/2008–30 and 30793/2010–30) into four groups, ten animals in each group. G1 SLD-A group were fed a standard laboratory diet (SLD). G2 SLD-B group were fed SLD and 12 h before rats were sacrificed diet was removed. G3...

Biogenesis and function of microRNAs can be influenced by genetic variants in the pri-miRNA sequences leading to phenotype variability. The aim of this study was to identify osteoporosis-related SNPs by affecting the expression levels of mature microRNAs.The first approach was to perform an association analysis of putative functional SNPs located in pri-miRNA sequences of bone-related microRNAs with the lumbar spine and femoral neck (FN) bone mineral den...

Objectives: Osteoporosis is a frequent cause of morbidity in boys with glucocorticoid (GC)-treated Duchenne Muscular Dystrophy (DMD). We sought to determine the frequency and characteristics of the two most debilitating types of fractures, vertebral and long bone (VF and LBF), in pediatric DMD.Methods: This was a prospective, bi-centre, single-visit observational study in boys 4 to 17 years of age with genetically-confirmed DMD. The bone health assessmen...

Cadmium (Cd) is regarded as a risk factor for various bone diseases in humans and experimental animals. To compare effects of different routes of Cd administration on femoral bone structure, ten 4-month-old male Wistar rats (group A) were injected intraperitoneally with a single dose of 2 mg CdCl2/kg body weight and killed 36 h after Cd had been injected. Ten 1-month-old male rats (group B) were dosed with a daily Cd intake of 30 mg CdCl2/l in drinking wa...

Bone marrow is the main hematopoietic organ of adults. There, hematopoietic stem cells from which all hematopoietic lineages can be generated are preferentially homing. Importantly, bone provides niches for early B cell differentiation and survival of long-lived plasma cells that produced antibodies. Thus, that perturbing bone homeostasis might impact B cell function and antibody production is a highly relevant hypothesis for patients receiving antiresorptive drugs.<p clas...

Receptor activator of nuclear factor kappa B ligand (RANKL)-induced activation of NF-κB and MAPKs signaling pathways is critical to osteoclastogenesis. Glossogyne tenuifolia has been used as an antipyretic, detoxication, and anti-inflammatory herb tea in Penghu Island, Taiwan. This study investigated the effects of G. tenuifolia ethanolic extract (GTE) on the formation of RANKL-activating osteoclasts and expression of signaling pathways using a RAW264.7 ...
